Hello,

I am using ls1012afrdm board . After successfully updating u-boot on board using codewarrior TAP device did not come up again.

Case 1:

Steps Followed :

1. Environment setup for flashing image using codewarrior TAP.
2. Open codewarrior studio and select target device,Activate it and clickon flash programmer.
3. You will get prompt to select action and execute it.
4. For u-boot i used attached binary at 0x100000 offset with erase and verify option.
5. It runs successfully. than i reset board. But it did not come up .

Case 2 :

After running above steps I tried to flash u-boot again using codewarrior studio but in between codewarrior studio stops.

Now when i am trying to connect device it gives me following error.

CCS: subcore error during multicore operation.

After running diagnostics i found following result.

Hello Kishan Patel,

Probably RCW on QSPI flash has already been broken.

Please refer to the procedure described in the thread https://community.nxp.com/message/852508?commentID=852508#comment-852508 to do recovery.

Thanks,

Hello yipingwang 

I have bare board with LS1012ASE7HKA referenced from freedom. When I am trying to connect JTAG using codewarrior TAP at speed of 16000 it gives following error.

On freedom board i can connect code warrior with same configuration.

What could be the possible solution to flash image.

1) Does CMSIS debugger comes into picture for connecting Codewarrior to Processors JTAG?

I have flashed CMSIS Debugger bootloader and firmware and it is working ok.

2) Is there any changes on processor PLS1012ASE7HKA and LS1012ASE7HKA to connect with JTAG?

3) Do I need to modify LS1012A_FRDM_init.py for connecting JTAG with processor LS1012ASE7HKA?

Power up sequence , Clock(25MHz), and reset configuration  match as per datasheet requirement.
